8 is a structural example of a component according to an embodiment of the present invention.

The component 150 may be designed to maintain software compatibility using a standardized profile (Component Package Library) and maintain the best component state. In addition, the component 150 may provide an environment capable of always maintaining compatibility between software through component update. In addition, the component 150 may provide an environment in which information that is urgent or that needs to be processed in a process can be processed through information exchange between components by managing subscriptions between components.

And, the component 150 may include a detailed configuration as shown in FIG. 8 .

The component 150 may package components using a middleware library, a component common library, and a component package library.

In this case, the component common library may store and manage commons of components according to standards. In addition, the Component Message Creator & Parser may process a message transmitted from the line management server 120 , the process terminal 140 , or another component 150 . In addition, the Component Subscription Mgr may manage event subscriptions. And, Control can process each control message.

In addition, the Event delivers each event message to the line management server 120 . In addition, Error/Status may transmit a message indicating the status of the component 150 to the line management server 120 . Also, the Component Common API may be a library API.

The component package library may group and manage components performing the same operation as a package even if the interface types are different.

For example, when a component is configured as a component processor for barcode printing and barcode printing, the interface type of the previously used barcode print and the interface type of the newly used barcode print may be different. In this case, the component package library can manage the existing barcode print and the newly used barcode print by grouping them into packages.

In this case, the component dependent function may be a target managed by a package for each component type, and the Component Package API may be a library API.

The Component HW Interface is a development environment according to the component development environment according to the hardware configuration, and can control equipment or receive and deliver events to the package library.

In addition, the component 150 uses the application for the hardware interface part (USB, RS232 or Bluetooth, etc.), the component common library, and the component package library to provide consistent data for components having different interface types included in the package. By applying it to the system as a model, it is possible to increase the reusability of the existing hardware.
